MACHINE FOR CUTTING HOOP-=lRON.

SPECIFICATION forming part of Letters Patent No. 391,586 dated October 23, 1888.

Application filed August 7. 1858. Serial No. 282,141. (No model.)

To all. whom it may concern:

Be it known that 1, James WILLIAM Coss- LER, a citizen of the United States, residing at Briar Hill, in the county of Mahoning and State of Ohio, have invented amew and useful Improvement in Machines for Cutting Hoop- Iron, of which the following is a specification.

My invention relates to improvements in devices for cutting hoop-iron; and it consists in certain novel features, hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view of my improved device. Fig. 2 is a vertical central longitudinal section. Fig. 3 is a plan view of the bed-block. Fig. 4 is a detail perspective view of the die or punch. Fig. 5 is a detail view of the dieblock with the dies removed, and Fig. 6 is a detail bottom plan view of the punch.

Referring to the drawings by letter, A desi gnates the die-block,which is supported upon a suit-able frame-work, (not shown,) and is provided at its center with the recess or dieopening B, and in its upper side with the re cesses G D on opposite sides of the said dieopening and communicating therewith. The recess D is rectangular, as shown, and an angular fixed die, E, is secured in this recess, the front edge of the said die being flush with one side of the opening B. The inner wall of the recess 0 is semicircular, and a semicircular tongue, F, projects into the opening B, as shown. A fixed circular die, G, is secured upon the upper side of the tongue F and enters the recess 0. An open space is thus formed between the two fixed dies having one straight side and a circular side directly opposite and projecting toward the straight side.

H designates the movable die or punch having a stem, I, on its upper end adapted to be secured in a suitable socket in a plunger (not shown) of any desired construction. The cutting end of this die or punch Hhas a flat face, J, and a semicircular concave face, K, directly opposite the fiat face J.

In operation one end of the hoop-iron to be cut into lengths is placed on the fixed die G, and the punch is then depressed so as to give a semicircular formation to the same end. The strap-iron is then pushed against a suitable gage in rear of the machine, the iron lying upon the dies E G and over the space B. The punch is then again depressed against the iron and forced through the die-opening B, thereby cutting the iron, the waste or sliver falling through the opening B. The rear piece of the iron, or that piece resting on the die IE, will have its front end provided with a straight or square edge, while the rear end thereof will have a convex edge.

The above-described operation is then repeated until all of the iron has been cut. 7

It will be seen from the foregoing descrip tion that I have provided a very simple and efficient device for cutting hoop or strap iron and similar material into lengths having ends of different shapes, and by the use of which I effect a saving of the time usually lost heretofore in shaping the ends of the sections.

My device is designed especially for use in making hoops for barrels. These hoops when applied to the barrel have their ends lapped, and the overlapped end is made convex, so as to form a neat finish. By the methods heretofore employed considerable time has been lost in shaping the ends of the hoop, whereas by my device the ends are shaped rapidly and with uniformity and precision. V

The fixed dies, being seated in recesses in the bed-block, will not project upward, so as to interfere with the easy travel of the iron be ing cut, and when worn out can be easily replaced by new dies. The scraps of iron are pushed through the die-opening by the punch,

obstructions.

Eaving thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination,with the bed-block hav ing a central die-opening and having recesses in its upper side adjacent to the die-opening, of an angular fixed die secured in one recess, and a circular fixed die secured in the other recess, substantially as set forth.

2. The combination, with the bed-block having a central die-opening and a tongue on one side of said dieopening, and provided in its upper sides with recesses communicating with the die-openings, of an angular die secured in so that the path of the iron is always free of one of said recesses and having its front edge flush with one wall of the die-opening, and the circular die secured upon the tongue and entering the other recess, as set forth.

3. The combination,with the bed-block having a central die-opening and provided with recesses in its upper sides, of an angular die secured in one recess, a circular die secured in the other recess and projecting into the dieopening, and a movable die or punch having one straight face and a semicircular concave face, as set forth.

4. The improved punch having a stem, I, a straight face, J, and a semicircular concave face, K, in combination with the dies, as set [5 forth.

- In testimony that I claim the foregoing as my own I have hereto affixed m y signaturein presence of two witnesses.
